ABSTRACT
Copper-catalyzed synthesis of disulfenylated imidazo[1,2-a]pyridines and indoles using elemental sulfur and haloarenes through one-pot, three component reaction by two C-S-C bond formations has been developed. The method has a broad substrate scope with a variety of substituted haloarenes. The conditions were also applied for the synthesis of benzothieno-imidazo[1,2-a]pyridines in excellent yields (99%) through intramolecular sulfenocyclization of 2-(2-halophenyl)imidazo[1,2-a]pyridines using sulfur powder.
ABSTRACT
In the present study, we have identified ten compounds, namely dodecanol acid, myristic acid, neophytadiene, palmitic acid, heptadecanoic acid, linoleic acid, elaidic acid, 3-7-dimethyl acid, stearic acid and methyl eicos acid, of the methanolic extract of Apamarga Kshara by GC-MS analysis. Apamarga Kshara has been reported to be active against cervical erosion. Major causal organism for cervical erosion is Trichomonas vaginalis. However, there is a paucity of information about the mechanism of action and inhibitory effect of the biologically active natural compounds presented in A. Kshara against this organism (T. vaginalis). Therefore, present investigation was conducted to observe possible interactions of these compounds on T. vaginalis carbamate kinase using molecular docking software 'AutoDock 4.2.' Identification of the amino acid residues crucial for the interaction between T. vaginalis carbamate kinase and these natural compounds is of due scientific interest. The study will aid in efficacious and safe clinical use of the above-mentioned compounds.
